Deep learning has emerged as a promising approach for solving complex partial differential equations (PDEs) using data-driven methods, particularly in scenarios where traditional numerical techniques face limitations. The 1D Burgers' Equation, which combines convection and diffusion terms, is a fundamental PDE used to model various physical phenomena, including fluid dynamics and shock waves. While analytical solutions for this equation are challenging due to its nonlinearity, specific cases do have exact solutions. This research systematically evaluates the effectiveness of two popular deep learning methodologies, Physics-Informed Neural Networks (PINNs) and Convolutional Neural Networks (CNNs), in solving the 1D Burgers' Equation. A particular focus of the assessment is to explore potential bias in the training dataset. The neural networks are trained using biased samples, and their results are rigorously compared with those obtained from unbiased samples. This investigation provides insights into the performance of these deep learning architectures and their sensitivity to the quality of training data. The research reveals significant sample bias effects on neural network (NN) models. Primitive bias notably impacts Convolutional Neural Networks (CNNs) more than Physics-Informed Neural Networks (PINNs). This is attributed to differences in loss function calculation, making bias selection more straightforward for CNNs. © 2023 Owner/Author.

Quantum computing is progressing at a fast rate and there is a real threat that classical cryptographic methods can be compromised and therefore impact the security of blockchain networks. All of the ways used to secure blockchain like Rivest–Shamir–Adleman (RSA), Elliptic Curve Cryptography (ECC) and Secure Hash Algorithm 256-bit (SHA256) are the characteristic of the traditional cryptographic techniques vulnerable to attack by quantum algorithms: Shor’s and Grover’s algorithms: can efficiently break asymmetric encryption and speed up brute force attacks. Because of this vulnerability, there exists a need to develop an advance quantum resilient blockchain framework to protect the decentralized ledgers from the future threats of the quantum. This research proposes Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD) and Quantum Random Number Generation (QRNG) as a formidable architectural integration, to fortify security of blockchain. Classical encryption is replaced with PQC, QKD with secure key exchange by detecting eavesdropping, and QRNG with improving cryptographic randomness to remove the predictable key vulnerability. Only with a small loss of transaction efficiency, we increase transaction encryption accuracy, key exchange security, and resistance to quantum attacks. In this quantum enhanced blockchain design, the idea is to preserve the decentralization, transparency and security and at the same time overcome the future quantum threat. By going through rigorous analysis and comparative evaluation, we demonstrate that the approach saves blockchain networks from the emerging quantum risks to make sure that the decentralized finance, smart contracts and cross chain transactions. © (2025), (science and Information Organization).

This study introduces some novel soliton solutions and other analytic wave solutions for the highly dispersive perturbed nonlinear Schrödinger equation with generalized nonlocal laws and sextic-power law refractive index. This equation models the behavior of complex wave propagation. The improved modified extended tanh function governs the transmission of various solitons with different effects. New optical solitons are constructed as bright solitons, dark solitons, combo bright-dark solitons and singular solitons. Furthermore, exponential solutions, triangular solutions and rational wave solutions are shown. The findings conferred in this article show a crucial advancement in understanding the propagation of waves in non-linear media. The study also includes modulation instability analysis to examine the stability of the derived wave solutions, supplemented by graphical simulations that depict their distinctive features. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

This paper presents a signal processing framework for automatic anxiety level classification in a virtual reality exposure therapy system. Two types of biophysical data (heart rate and electrodermal activity) were recorded, pre-processed and passed through a feature extraction procedure that provided input for the real-time anxiety level classification algorithm. We showcase the mathematical and engineering techniques behind the procedures and conclude with the challenges encountered in our research and future development ideas. The proposed method provides a good estimate of the level of anxiety while having at the same time a reduced level of complexity, allowing implementation on equipment with limited computing resources. © 2024, Politechnica University of Bucharest.

Most of the current display devices are with eight or higher bit-depth. However, common multimedia tools cannot achieve this bit-depth standard. Image de-quantization can improve the visual quality of low-bit-depth images for displaying on high-bit-depth screens. To achieve image de-quantization, we propose the DAGAN algorithm to perform super-resolution on image intensity resolution, which is orthogonal to the spatial resolution. DAGAN employs Generative Adversarial Networks (GANs) and achieves photo-realistic de-quantization via an end-to-end learning pattern. Our DAGAN consists of a dense residual non-local network (DRNN) and a discriminative network. We design the Dense Residual Non-local Block (DRNB) to construct DRNN. DRNB utilizes the dense network architecture to enhance the representation ability and employs the non-local module to extract features that capture long-range dependencies between pixels. Furthermore, we use the adversarial learning framework to promote our DRNN to produce high-quality natural images. Experiment results on several public benchmarks prove that our DAGAN can generate photo-realistic high-bit-depth images without quantization artifacts. © 2024 SPIE.

Social media platforms help users share opinions and find new information but also spread rumors, which misinforms the public. These rumour threads often prompt users (called guardians) to respond with fact-checking articles to debunk or verify the rumour. We examine how general users’ and rumour starter respond to these fact-checking (FC) comments. This study explores these aspects by analysing users’ textual and non-textual engagements. These engagements are examined across three main factors: platforms (Twitter and Reddit), rumour topics, and the primary medium (text, image, video, and GIF) in the rumour post. We observed minimal differences across primary mediums by analyzing 147K news posts and FC comments with 20.7 million replies. Furthermore, we found that Reddit users engage with FC comments more than Twitter users in terms of likes and the rumour starter’s reply-back rates. We found that no general users engaged with the rumour post before and after the guardian intervention. The most significant differences in the emotive characteristics of replies were across topics, with rumour starters expressing more anger, disgust, and offensive language when discussing rumours about terrorism and racism. These emotions indicate the backfire effect. Our findings raise concerns about the effectiveness of fact-checking interventions in updating misinformed users. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Detecting vulnerable smart contracts has a direct effect on blockchain security because it helps users avoid using these contracts. In this study, the problem of vulnerability risk for blockchain smart contracts is introduced. Moreover, an effective criterion for its estimation is devised. With this criterion, to estimate the risk of an unknown smart contract, linear discriminant analysis of smart contracts and distances to their nearest neighbors were exploited. Although deep learning is not used in the proposed criterion and it requires little training data, it provides a realistic risk estimation of smart contracts. The experiments conducted on a real-world dataset of Ethereum blockchain smart contracts, including both vulnerable and safe contracts, show the acceptable performance of the proposed criterion. Moreover, the performance of the proposed criterion is superior to that of existing criteria in other areas of risk estimation. © 2025 IEEE.
